What if any problems are people seeing out of their cam-swapped Coyote valvetrain since we've had aftermarket cams out for a while? In the past, Ford modulars have had the bad habit of.. well how do you say it, becoming ticking time bombs once you start swapping out valvetrain components. I believe that with cams like the Comp Cams choices that do not require valvespring swaps, these problems are less likely to show up in the Coyotes, but I'm just trying to gather info/facts for my future Coyote-powered Mustang purchase :coolman:
